Bret would find himself at the edge of the northern forest from his hometown of Rock (Towns are named after Pokémon types in this region). The forest wasn't anything special in of itself, which meant that there were few trainers who would go there either for catching Pokémon, or doing any kind of job. This, made it the ideal location for Bret's graduation test, where he had to find some form of contribution to the lab back in Rock. Be it a Pokémon of an unusual color or behavior, or the discovery of an old ruin or treasure. Pretty much any discovery, no matter how small would count, letting him graduate from the academy and officially get his trainer ID certified beyond it's current, provisional status. With his hometown Rock behind him, and the norther forest in front of him, his adventure began.
